Several researchers have stated that parasites can alter the behavior of their hosts, in order to increase the transmission rate, principally when prey-predator relationships are a reliable way of infection transmission. The aim of this study was to verify the occurrence of changes in anxiety and short-term memory patterns in experimentally infected Mus musculus by Toxocara canis and/or Toxopla...

31 Pathological anxiety is thought to reflect a maladaptive state characterized by exaggerated 32 fear. Naturally occurring perturbations that reduce fear can be crucial in the search for new 33 treatments. The protozoan parasite Toxoplasma gondii invades rat brain and removes fear of 34 rats for cat odors, a change believed to be parasitic manipulation of host behavior aimed at 35 increasing p...

background: the effects of extremely low frequency electromagnetic fields (elf-emf) on toxoplasma gondii have not been explained yet. the aim of this study was to assess the possible effects of elf-emf on growth, survival time and viability of toxoplasma gondii . in addition, the life span of toxoplasma infected animals was investigated. methods: sixty adult male balb/c mice were used for in vi...

ocular lesions are a common manifestation of toxoplasmosis in cats. in this survey, 10 healthy syrianmice were infected through intraperitoneal inoculation of bradyzoites of toxoplasma gondii (tehran strain).mice were killed 30 days after inoculation and the suspension of their brains was prepared, after confirmationof the infection. seven kittens were fed with the infected mice brain suspensio...

background: soil structure is mainly composed of sand, silt, clay, and organic materials. organisms can live in the soil. the large number of stray cats in the cities of iran is a major environmental and health problem. toxoplasma oocysts are shed with the feces of cats, so soil is known as a potential source of transmission of toxoplasmosis. the aim of this study was to determine the soil cont...

objective(s):there are supportive evidences about the possible role of latent toxoplasma. gondii infections on the behavior and neurologic functions, such as increased dopamine levels in the brain. the aim of this study was to examine anti-toxoplasma activity of aripiprazole that is an atypical anti-psychotic drug in mice. materials and methods: mice were randomly divided into four groups, incl...

QUESTION One of my female patients was tested for Toxoplasma and found positive for immunoglobulin G (IgG). She is planning to get pregnant soon. What are the risks for her and her baby? ANSWER Up to 25% of Canadians are IgG-positive for Toxoplasma due to past exposure. Immunoglobulin M (IgM) titres indicate current infection. Toxoplasma gondii is an obligate intracellular protozoan that has ...
